FERDINAND rRANCIs BRUCRER, or AKRQN, omo, AssIGNoR 'ro THE MILLER RUBBER COMPANY, A CORPORATION or oHIo.

To all whom it may concern: Be it Aknown that jI, FERDINAND F. BRUCKER, citizen of the United States, re-

siding'at Akron, Ohio, have invented cer-i.`

,tain newand useful Improvements in Tre- Building Apparatus, of which the following is a specification.

My 'present invention relates to improve` ments in apparatus for causing frictioned `fabric such as employed in forming'or building pneumatic vehicle tires to be smoothly and effectively applied to the rotary cores or circular mandrels, and the invention has among others for its objects to pro-vide a simple, durable and efiicient form of apparatus,.. capable of being easily controlled by a single operator to secure the application\of the fabric in a smooth andy eective manner. f

The in-vention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

A form of apparatus constructed in accordance with my invention is illustrated in 'the accompanying drawings, "in which Figure 1 isv a plan view;

Figure 2 is a side elevation;

Figure 3 is a front elevation;

Figure 4 is part of Figure 1; and

Figure 5 is a section of Figure 4,'on line' 'lhe apparatus above indicated is intended to press oi draw the fabric down -smoothly and firmly around the ring core or mandrel after it has been applied thereto or wound thereon in the form of a strip or strips in any suitable manner.

lnl Figure 1 a portion of the mandrel is' indicated conventionally at 1, and the fab-ric in theposi'ticn it assumes on being wound thereongid'before being pressed or spun down around the core, at 2. Y

The pressing or spinning d own of the fabric is aocomplishedby a pair of wheels or discs 3 which are mounted for free rotation on a pair ofarms 4 which have their Shanks 4a slidably mounted in brackets 5` swiveled on the ends of arms 6. l

Springs 7 encircling the shanks 4a and bearing against collars or flanges 8 there- 'on permit a yielding action of the Shanks Application led September 5, 1913. Serial No. 788,306.

4a and consequently the discs 3 when passed i by splices in the fabric 2.

The arms 6 are mounted upon a slidable carriage 9 supported by the frame 10 of thc machine, so that they may be m'oved toward i.

and from the core; and in order that they v may be simultaneously separatfid sufficiently to act at the proper points ons the core and pressed thereagainst to effect the shaping or spinning action I mount. them rigidly upon hollow shafts 11 journaled in the frame of the carriage and carrying intermeshing gears 11a which cause them to be rotated in unison. One of these shafts carries at its lower end, a bevel gear 12 which meshes with a verticallydispod bevel gear 13 slidably keyedy toa shaft 14 to which is afhxed an' arm 15. This, in turn, is connected by a link 16 with arm-17 of shaft 18 to which is connected treadle lever 19. This'treadle lever 19 is normally held elevated by springs 20,

and when in this position holds the arms 6 A separated.` By this construction arms 6 may be moved independent ofjthe rotating motion of arms 4 as Il` will further explain in a later paragraph of this description.

When the Vcarriage has moved forward until the discs are in proximity to the core, the operator places his foot on the treadle anddepres'ses ituntil the discs are pressed towards each other, causing them to impinge against thel fabric on the core at the properl i distance on each side of the center thereof, and governs they pressure of the discs o n the fabric by the amount of pressure of his foot.

Power is imparted to move the carriage forward bya wheel 21 which may be driven from any convenient source of power, which wheel is fast on a shaft 22 carrying a helical gear'22a which meshes with a helical gear 23 on screw shaft 24 extending longitudinally of the machine. The carriage is provided at a suitable point with two half Anuts 49 operated by hand lever 26 so thatwhenl the half nuts and screw are brought into engagement, the carriage 'will be fed forf ward.

The half nuts 49 'are each provided with a pin 48 which extends upwardly through lateral guiding slots in carriage9 and scroll slots' in a circular Cam 47 is sunk in a recess in carriage 9 and rigidiy rection of hand lever 26 andcam 47 causes the half nuts 49 to engage withfscrew 24 by vio reason 'ofthe pins 48, carried by half nuts 49 being forced together bythe scroll slots 5 3 in cam 47. A

Stud 46 is surrounded by a coil spring 50.- @ne end of coil spring 50 is rigidly conu nected to cam 47. The other end is rigidly connected to barrel 51 which surrounds coil spring 50 and supports stud 46. Coil spring` 50 resist-s motion of cam 47 in a clockwise direction and is of sufficient strengthto dis'- en age half nuts 49 from feed screw 24.

am 47 is .provided with a notch 52 Yin its periphery and a latch 44 slidably mounted inA a recess in carriage 9 and pressing radially against cam 47 is so placed as to enter l mit 57.

-notch 52 in cam 47 when half nuts 49 are.

engaged with the. feed screw 24,'s'aid pressure being produced by a spring 45. Latch -44 locks half nuts 49 in engagement with feed screw 24 holding them in said lengagement until it isradially withdrawn.

' 4Latch 44 is provided with annpwardly projectin pin 56 which is engaged by a slotted -ho e in a lever 42. Lever 42 is-pivotally connected at its center to carriage 9 by a screw 43 and has a bent end 55. Frame 10 is provided lwith a longitudinal T slot 56X and a movable stop 41 is clamped to frame 10 b top 41 is provided with an in- 5 clined vertical surface of-such shape as to enough for lever 42 to cause Alever 42 to withdraw latch 44` from cam 47 when the carriage has ,moved far impinge against sto VStop' 41 may be locked in such a position that when discs 3 have just vaccompl1shed the applying of the fabric the half nuts 49 will be disengaged.`

When the half nuts 49 are-'disengaged from the screw, the carriage is automatically retracted bya cable 27 whichV is acted upon by'a weight 28,`one end of the cable being'y fast to a lbracket 29 and thence passing 'around pulley 30 on vthe weight andover` pulley 31 on the machine frame tothe car- `riage,. to which. it is secured as indicated It is .necessary'in order to secure the best results, that the' angle of the'discs `3 should be changed as they progress around the core, so as to 'maintainthem at.. about the same' angle or tangent ,to the periphery of the core, or to cause them to act von'the fabric' always atthe most efficient angle. It is also K a great advantage to be able to maintainv this angle when stitching or spinning the means of this slot and a bolt and Lacasse fabric around the beads of the different sloT es of tires.

To accomplish this l connect the rear ends of the arms' 4 by links 33, preferably adon a shaft journaledin bearing bracket 39 and carrying' hand wheel 40. The other disc-35 is free to revolve on shaft 36 and is driven by disc 35.

By rotating hand wheel 40 the angle of the discs may -be changed inde endent of the movement of arms 6 to suit t e operator and as the shapingof the fabric progresses. lt will be observed that instead of moving `the carriage supporting the fabric shaping or forming rollers towards the core, the latter might be movedtowards andfrom the support for the fabric shaping devices, but the former is' preferable and hence is the 'construction which l particularly describe.

lt will be understood that I do not limit myselfvto the precisedetails of construction ,herein shown and described, as various modifications thereof might be made without departing from the spirit of my invention.y
